TY, Bev & Tarev. (That rhymes.) About to find out if any are not hardy. All I can do is cover that with a sheet, and put a tub of warm water under it. Worked at 30 degrees so far, last week. I hope to do something a little more permanent next year, with whatever's left. I had fantasies about bringing that inside when I put it together much earlier this year. Folly! It would take 2 men to move it, and it has ants. And what window would I kick 25 other plants out of to put it by? Learning experience...!
